How Do I Import Linetypes in AutoCAD?

AutoCAD is a powerful software that allows users to create precise and detailed drawings. One of the key features of AutoCAD is the ability to define and use linetypes.

Linetypes are patterns that can be applied to lines, arcs, and other objects in your drawings. While AutoCAD provides a variety of linetypes by default, you may find the need to import custom linetypes into your project.

Importing Linetypes

To import linetypes in AutoCAD, follow these simple steps:

Step 1: Create a LIN File

The first step in importing linetypes is to create a .LIN file. This file will contain the definition of your custom linetype. You can create this file using any text editor such as Notepad or Notepad++.

  • Note: The .LIN file format follows a specific syntax, so make sure to adhere to the formatting rules when creating your custom linetype definition.

Step 2: Load the LISP Routine

After creating the .LIN file, you need to load a LISP routine that will import your custom linetype into AutoCAD. LISP (LISt Processing) is a programming language used by AutoCAD for customization purposes.

  • Note: The LISP routine should be compatible with your version of AutoCAD. You can find various LISP routines available online or consult the documentation provided with your version of AutoCAD for compatible routines.

Step 3: Run the LISP Routine

Once you have loaded the appropriate LISP routine, you can run it to import your custom linetype. In AutoCAD, type “APPLOAD” in the command line and press Enter.

This will open the “Load/Unload Applications” dialog box. Click on the “Contents” button and navigate to the location where you saved your LISP routine. Select the routine and click “Load”.

Step 4: Define the Linetype

After loading the LISP routine, you can define your custom linetype in AutoCAD. Type “LINETYPE” in the command line and press Enter.

In the Linetype Manager dialog box, click on the “Load..” button and locate your . Select the file and click “Open”. Your custom linetype will now be available for use in AutoCAD.


Importing linetypes in AutoCAD allows you to customize your drawings and add unique patterns to your lines and objects. By following these steps, you can easily import custom linetypes into your project, expanding your options for creating visually appealing designs.

Note: It’s important to ensure that any custom linetypes you import comply with copyright laws or licensing agreements.
